In a students seminar we tried to calculate basic network metrics using the
igraph library. I also called the statnet library but used igraph functions
for the estimations. When comparing my output with that of my class mates
who didn't call statnet, the values were different. I didn't get any
warning or error but the values were wrong. I tried to solve this by
removing the statnet library (I actually delete it completely from my
computer) but I kept getting the same wrong values. I tried it in other
computers and I got the same wrong values. Has anyone had similar issues
when using igraph and statnet? Is there an explanation for this? Any ideas
on how to solve it? I am new to igraph and other network packages, so I am
not sure if this has been discussed before, but I haven't been able to find
anything yet.
Best wishes,
Silvia

the thing is, I still cannot run this code, because I don't have
"Horse.csv". Also, you did not say why do you think the output is bad, and
what do you think would be the correct output. For the graphs I have tried
igraph and statnet give the same results for degree() and betweenness().
Please also include the output of the sessionInfo() function, because
statnet and sna only recently have a namespace, and it matters which
version you use.
